Fomrez UL-2 catalyst Dibutyltin carboxylate Crompton-OSI Specialties Catalysts / Accelerators / Vulcanizing agents >> Organometallics PU - Prepolymers Dibutyltin Carboxylate catalyst is recommended for use as a replacement for dibutyltin dilaurate. organotin carboxylate This catalyst is generally more compatible than dibutyltin dilaurate with the “B” component of polyether-based urethane systems. Unlike some urethane systems catalyzed with dibutyltin dilaurate, exhibit no separation or haziness resulting from catalyst incompatibility. Catalyst has a much lower freezing point then DBTDL. Dibutyltin Carboxylate catalyst used as a replacement for dibutyltin dilaurate. Offers low freezing point, good compatibility with the “B” component of polyether-based urethane systems. Exhibits no separation or haziness resulting from catalyst incompatibility.
